Wiseco Toyota 4EFTE 74.50mm Bore -2.5cc 1.1 Piston Kit

If you're building a high-performance Toyota 4EFTE engine, this Wiseco piston kit is a solid choice. These are forged pistons, meaning they start as a block of 2618 aluminum that's heated and then pressed into shape. This process gives them improved tensile strength over cast pistons, making them well-suited for the demands of racing and severe duty applications.

Wiseco machines these pistons right here in the USA. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown and forced pin oiling are also notable features that contribute to their durability under heavy load.

This kit includes four pistons, each with a 74.50mm bore and a -2.5cc dish. The compression height is 29.90mm and the pin diameter is 22.00mm. Keep in mind these are not CARB approved and cannot be shipped to California. They are designed for sport compact applications and are built to withstand heavy to severe duty performance builds.
